Acquisition Setup
Selecting the second tab of the main window displays the Acquisition Setup window. The four main parts of
this window include setup parameters for triggering and configuring the scan. These settings will be used
when an acquisition-to-disk is started by selecting “Acquire” (last item on the toolbar). When the trigger is
satisfied, the scans are collected at the selected scan frequency and stored to disk in the designated file.
